Pine Phone Pro audio on phone calls: discussion, support and tips
2023 Dec 11 - Danctnix Arch with Phosh [SOVLED]

I did an update "sudo pacman -Syu" and people told me my phone calls sound like I am on a freight train.

BEFORE update 
  cset "name='ADC Capture Volume' 160"
  cset "name='Mono ADC Capture Volume' 160"

AFTER update to fix voice calls
  cset "name='ADC Capture Volume' 0"
  cset "name='Mono ADC Capture Volume' 0"

*I use the internal speaker, not the "speaker" button*
Yes after megis 6.5something things have changed and audio is routing differently.

What mikehenson wrote is correct answer for a super dirty nearly usable workaround. It is still best option what you can do easily...

Fun thing is that when you set:
cset "name='ADC Capture Volume' 0"
(in /usr/share/alsa/ucm2/PinePhonePro/VoiceCall.conf)
You are settings the microphone to 0 - so it should be completely silent.
While it sill too loud (you can use it yes but the receiver will definately hear you because it really is loud)

For eveyrones information this does not actually do anything:
  cset "name='Mono ADC Capture Volume' 0"
You can put any value you want there but it does not do anything in voice calls Big Grin
I have recently installed the newest (12/22) edge version of pmOS and the mic is no longer working on phone calls. Calls were working fine for roughly the last year. I am wondering what has changed. It would be nice to know how megi's new kernel has changed the audio routing. My audio does not sound like a freight train. It is simply quiet. Sounds like this is different from what is being described by mikehenson.

edit: My ADC Capture Volume is set to 160 in /usr/share/alsa/ucm2/PinePhonePro/VoiceCall.conf.
